Computers may have a short history but prior to their development, there
were many other ways of doing calculations. These calculations were done
using devices that are still used today; the slide rule being a perfect example,
not to mention the ten fingers of the hands. These machines, unlike computers,
are non-electronic and were replaced by faster calculating devices. It wasn’t
until the mid-1940s that the first digital computer was built. The post-war
industrial boom saw the development of computers take shape. By the 1960s,
computers were faster than their predecessors and semiconductors had replaced
vacuum tubes only to be replaced in a few years by tiny integrated circuit
boards. Due to microminiaturization in the 1970s, these circuits were etched
onto wafer-thin rectangular pieces of silicon. This integrated circuitry is known
as a chip and is used in microcomputers of all types.
It has been forecasted that exceptionally faster and smaller computers will
replace those in use today.
